VAPOR-LAMP BURNER.

Specification of Letters Patent.

Patented May 31, 1910.

Application filed August 21, 1909. Serial No. 513,941.

To all whom it may concern:

Be it known that I, HARRISON GRrswoLD, a citizen of the United States ofAmerica, residing in the borough of Manhattan, city, county, and Stateof New York, have invented an Improvement in Vapor Lamp Burners, ofwhich the following is a specilication.

My invention relates to a. vapor lamp burner having a stationary wickand preferably using' alcohol as a burning fiuid; such vapor lamps asare usually employed for heating and cooking.

ln lamps of this character it has heretofore been diflicult if not quiteimpossible to control the height of the flame, or in other words, tocontrol the surplus vapor accumulating from the vaporization of thefluid in the presence of heat; the fact being that the vapor frequentlyburns fiercely, increasing the size of the flame often to the dangerpoint, all of which it is the object of my invention to overcome.

In carrying out my invention, I employ devices adjustable in characterproviding for the discharge of any surplus vapor accumulated in the bodyof the burner, which discharge is at a place appreciably distant fromthe flame so that the escaping vapor does not add t0 the volume of theflame. This I accomplish by the employment of telescoping tubes, theouter one of which passes through and is secured to the burner bodyabove the stationary wick and is provided with a series of holestherethrough within the limits of the burner, with a tube at one endprojecting beyond the burner.

The interior telescoping tube is open at the inner end and closed at theouter end preferably with a knob to be grasped by the lingers for movingthis tube longitudinally, and a series of holes are formed along in thisinner tube preferably of increasing diameters, which when beyond thefree end of the outer tube provide for a regulatable escape of thesurplus or pent up vapor.

In the drawing, Figure l is an elevation representing the device of myinvention. Fig. 2 is a plan of the same and Fig. 3 is a vertical sectionand partial elevation on the dotted line zc, fc, of Fig. 2, and Fig. 4is an inverted partial section at about the line of the outer and innertelescoping tubes.

a represents the cylindrical reservoir for the burning fluid. This isprovided with a central opening having a surrounding flange al and thereservoir is supported by members having parts 2 secured to the sides ofthe reservoir, legs 3 supporting the reservoir in a slightly elevatedposition and arms 4 rising from the parts 2 and bent outward and overfor supporting thereon a vessel holding material to be heated by theburner. T prefer to upturn one leg 5 to form a handle for carrying thedevice about.

represents the burner body and c a dishing-cover secured to and aroundthe base of the burner and adapted to fit the central opening of thereservoir and to frictionally Contact with the surrounding flange al ofsaid opening, and this dishing-cover is provided with a tube c1 whichextends down therefrom into the fluid of the reservoir. The burner isformed with holes 5 and 6 providing for the exit of the -vapor to beburned.

Z represents a wick of liberal proportions secured in a stationaryposition to and within the burner.

The special features orf my present invention relate to the outer tube cand inner tube f. The outer tube e extends across Within the burner Z)and projects from the burner to an appreciable extent and is securedrigidly to the burner and itI is provided with holes c1 within thelimits of the burner into which the vapor within the burner entersfilling the tube. The tube f fits snugly within the outer tube c. It isopen at the inner end and closed at the outer end with a finger-knob f2and it is provided with series of holes f1.

Fig. 3 shows the tube f as pushed entirely into the outer tube c butFigs. l, 2 and 4 show the inner tube as partially pulled out of theouter tube c and in so doing several of the holes fl of the inner tubeare shown as exposed.

ln the operation of the device it is preferable at the outset to pressdown the burner with its cover or upward against the bottom of thereservoir and in so doing compel air within the reservoir to force asmall quantity of fluid up through the tube cl into the dishing cover c.This may be lighted with a match and while burning heats the burner,increases the vaporization of the fluid and at once also lights theburner. The flame goes out from the vapor burning in the dishing coveras soon as the 'fluid is consumed and thereafter the vapor only burnsfrom the burner. Should the flame get too high the inner tube is pulledoutl exposing a single or any desired number of the holes 7'1 in thesaid tube. ln doing this7 surplus vapor is allowed to escape throughthose holes into the atmosphere at a place distant from the flame; Wherethe vapor being lighter than air u'ill ascend Without burning and inthis way by the longitudinal movement oi the inner tube and theuncovering of any desired. number' of holes for releasing the pent uptluid is the height of the tlaine regulated, for unless the llame is toohigh the inner tube j" need not be moved longitudinally to expose any ofthe openings, but in ease the tiziano is too high the escape ot the pentup vapor through the holes of the inner tube vvill at once loiver the'thune and consequently keep it Within sate limits. When the thune isput out the inner t-ube should be pushed into the outer tube e :is tarpossible so as to prevent the escape and eedless Waste of the vapor.

l claim as my invention:

l. ln a vupor lamp burner7 the combination uit-h a reservoir and uburner, ot' a device secured to the burner and having' openings and asecond device occupying a eoaeting relation With the first device andalso having' o ieniugs und slidubly movable in relation to the iirstdevice und in its movement discovering' the openings provided thereintor permitting the escape ot the pent up vapor.

2. ln a vapor lamp burner the combination with u reservoir, a burner anda stationary wick, ot a tube secured to the burner passing throughwithin the same and projecting and provided with openings in the tubeWithin the burner, and a slidable tube eo-ecting with the said tube andadapted in one position to prevent the escape of the ranged therein andvarying in size and providing with the longitudinal movement ot' saidtube for exposing any desired number of said openings permitting theescape ot the pent up vapor 4f. In a 'vapor lamp burner and incombination, a reservoir, a burner and stationary Wick,Y teleseopingtubes the larger ot which extends across Within the burner through thewall at one side and projects and is provided With a series ot' openingsWithin the limits of the burner which permity the pent| up vapor to passinto said tube, the inner tel/scoping tube titting snugly Within theouter one, and a finger-engaging knobclosing its outer end, said innertube being pro` vided with a series of spaced apart openings ot varioussizes which may be exposed with the longitudinal niovement ot the innertube, providing tor the escape ot' the peut, up vapor in the burnerintov the open air.
